Just to share some experience for those wanting to mod their Rx 5700 xt reference card with AIO using kraken g12:-
-AMD bracket that came with kraken g12 have an offset around 1mm for the holes. It would not fit perfectly unless being forced with screw or cut in half.
-VRM temperature is good even w/o heatsink. I had mine around 70c in H210i casing.
-VRAM temperature is terrible w/o heatsink. I saw mine reached 96c. Low profile Heatsink is needed if u wish to install it on your ram. 4x 5mm height, 2x 4mm heigth(for 2 vram facing side panel). Else it wont fit due to close proximity to AIO cold plate.
-flatness of the AIO cold plate plays significant role, i saw the delta between Edge temp and Junction temp not more than 7c apart with proper mounting.

My gpu can barely breath with this casing. Prior to this i've used reference Rx 5700 xt, but the temperature is quite bad unless i undervolt it to 1050mv and 1850mhz target clock but still need to have the fan run @2600rpm for decent temp (80s edge, 100s junction)

yep, luckily the bottom plate have holes. But still not sufficient.

I somehow manage to make it work. Since there is quite few ventilation holes on the psu shroud, i changed my psu to SFX psu just to make the gap between shroud and psu bigger for ventilation.

Also added 2 hard foam acting as gpu support. Picture for reference. Now temp is in the lower 70s for edge, while junction temp around 95~100c. GPU clock stays around ~2030mhz.

re-visit RX5700XT+modded kraken g12. Using an old AIO(antec kuhler h2o 620) i had lying around, the temperature is still crazy in a compact case. In my case, i'm running it in H210i with 3700x cooled by 240mm rad at front intake.

After some undervolting, i think i can live with it. ΔTemp not that big as well between edge and Tj. PC is super silent now

yep not that great, 90c for edge temp with AIO. Prior to this with stock cooler edge temp often reach 110c with default fan curve. If i ramp it up to 60% fan speed it hovers around 100c.

only problem is with kraken g12 is, it doesnt have active cooling on VRAM. On a hot day VRAM sometimes reach 100c, shy 5c from upper spec limit.(I had low profile copper heatsink on the VRAM)

In this case i blame it on the reference blower design for the bad temp. Even the AIO im using is quite crappy for today standard.

I have another rx5700xt on another system, but it's Asus ROG strix. Temperature on that one is around 70c edge temp/90c junction temp@2.1ghz, far much better than the modded one with AIO.

Yep, planning to wc in the near future
